Abstract

Methods and systems for collecting, tagging, searching for, retrieving, inventorying, and transferring evidence by law enforcement officials are described, in which RFID tags associated with pieces of evidence can be interrogated to assist in locating information relating to that evidence.

Claims

1. A method for converting a collection of non-RFID tagged pieces of evidence related to law enforcement to RFID-tagged evidence related to law enforcement, comprising the steps of:

(a) providing a piece of evidence related to law enforcement that includes a non-RFID tag;

(b) obtaining information From the non-RFID tag;

(c) inputting the information into a processor;

(d) writing the information onto an RFID tag;

(e) associating a database record with that RFID tag; and

(f) associating the RFID tag with the piece of evidence related to law enforcement.

2. The method of claim 1, wherein steps (b) and (c) comprise scanning a bar code on the non-RFID tag.

3. The method of claim 1, wherein step (b) comprises reading information from the non-RFID tag visually.

4. The method of claim 1, wherein step (c) comprises typing information using a keyboard.

5. The method of claim 1, wherein step (c) comprises using a touch-panel display.

6. The method of claim 1, wherein the method further includes the step of associating the RFID tag with a container for the piece of evidence prior to step (d).

7. The method of claim 1, wherein the method further includes the step of printing information on a surface selected from major surfaces of the RFID tag, a label, and a container for the evidence.

8. The method of claim 1, wherein the method further includes the step of entering information that relates to the piece of evidence into the database record.

9. A method for converting a collection of non-RFID tagged pieces of evidence related to law enforcement to RFID-tagged evidence related to law enforcement, comprising the steps of:

(a) providing a piece of evidence related to law enforcement that includes a non-RFID tag, followed by the step of

(b) obtaining information from the non-RFID tag, followed by the step of

(c) inputting the information into a processor;

followed by the following steps in any order;

(i) writing the information onto an RFID tag; and

(ii) associating a database record with that RFID tag; and

(d) associating the RFID tag with the piece of evidence related to law enforcement.

10. A method for converting a collection of non-RFID tagged pieces of evidence related to law enforcement to RFID-tagged evidence related to law enforcement, comprising the steps of:

(a) providing a piece of evidence related to law enforcement that includes a non-RFID tag, followed by the step of

(b) obtaining information from the non-RFID tag, followed by the step of

(c) inputting the information into a processor;

followed by the following steps in any order;

(i) writing the information onto an RFID tag;

(ii) associating a database record with that RFID tag; and

(iii) entering information that relates to the piece of evidence related to law enforcement into the database record; and

(d) associating the RFID tag with the piece of evidence related to law enforcement.

11. A conversion station for converting a collection of non-RFID tagged pieces of evidence related to RFID-tagged pieces of evidence related to law enforcement comprising:

(a) an information receiving system into which information related to a piece of evidence related to law enforcement may be input;

(b) an RFID tag feeding mechanism to receive and advance RFID tags to a tag programming zone; and

(c) an RFID writer including an antenna adjacent the tag programming zone, for writing the information to the RFID tag positioned in the tag programming zone.

12. The conversion station of claim 11, wherein the conversion station further includes a supply of RFID tags positioned within the RFID tag feeding mechanism.

13. The conversion station of claim 12, wherein the conversion station further includes a processor and a database, and the processor associates the RFID tag with a database record.

14. The conversion station of claim 11, wherein the database record includes information about the piece of evidence.
